Adding more permits debug statements to better diagnose permit issues by devinbost · Pull Request #10217 · apache/pulsar

devinbost · 2021-04-13T19:26:29Z

This PR just adds debug statements whenever the broker updates its permits in broker.service.Consumer and in PersistentDispatcherMultipleConsumers. It also adds batch sizes to some of the debug log statements.
That will help with the forensic analysis of problematic permit behavior.

@merlimat @eolivelli Since it's not easy to get debug logs from functions due to #3259, I added more logs to the broker instead.
